Are you looking for a switched ignition wire? Or an actual remote turn on lead?
A remote turn on lead SHOULD turn on and off with the radio. You turn off the radio, the wire loses power...
The safe bet would be to splice it directly from the radio harness... To find it, get a hold of a digital multimeter and start testing each wire til you find one that ONLY shows +12V (Actually somewhere along the lines of 14V, but who's counting...) when the unit is turned on. When you push in the volume knob to turn off the radio, the wire will lose power.
Once you find this wire, do not think the test is over... Next, put in a CD... If the wire maintains +12V, you have found the remote turn on wire. If it loses 12V when you put in a CD, then you have found an output for remote actuation for a power antenna, or XM receiver box... Something like that...
You can use a switched ignition source, but the amp will remain powered up the entire time the ignition is turned on, regardless of wether or not you have the radio turned on.
I would get it behind the radio... If a true remote turn on signal exists anywhere in the ION, that's where it is...
